[ https://issues.jboss.org/browse/WFLY-9081?page=com.atlassian.jira.plugin.... ] cnsgithub cnsgithub commented on WFLY-9081: ------------------------------------------- I think something related to this, broke something with WF12 when using Spring. Currently i can't provide a *.war to test but a class residing in the *.war classes path is no longer recognized. import org.springframework.web.WebApplicationInitializer; public class MyWebApplicationInitializer implements WebApplicationInitializer 09:52:16,244 INFO [io.undertow.servlet] (ServerService Thread Pool -- 51) No Spring WebApplicationInitializer types detected on classpath org.springframework.web.SpringServletContainerInitializer @Override public void onStartup(@Nullable Set<Class<?>> webAppInitializerClasses, ServletContext servletContext) ->> WebAppInitializerClasses does not contain the MyWebApplicationInitializer anymore Ultimately this call is coming from: WarMetaDataProcessor I hope this is enough to find the cause of this. The same configuration worked fine with WF11 Final. -- This message was sent by Atlassian JIRA (v7.5.0#75005)
